Giffords still struggles to speak and walk, but has become a leader of Americans for Responsible Solutions, a national organization she founded with her husband, Mark Kelly, to rival the powerful pro-gun lobby.
The group struggled to bring about any major change at the federal and state level in its first year of existence, but the couple is confident they laid the groundwork for success in future election cycles.
"The legacy of any day where there's a mass shooting and loss of life is, I think, a chance to reflect on who these people were and what they did, particularly the people who died," Kelly, a former astronaut, said in an interview with The Associated Press on the eve of the anniversary. "But it's also a chance to look forward and see how we can make changes and reduce the numbers of instances like this that we have."
Skydiving experts say it's relatively safe for someone with Giffords' physical struggles to make a jump. Nancy Koreen, a spokeswoman for the United States Parachute Association (USPA), says almost anyone — depending on the extent of their disability or injuries — can do a tandem or solo jump. It was not immediately known what type of jump Giffords plans to do. But a tandem jump, where the jumper dives strapped to an instructor, would require less training.
"On a tandem skydive, the instructor manages most of all the physical side of the skydive. A lot of people with physical disabilities like paralysis or multiple sclerosis or other disabilities that make them unable to walk, they safely do tandem skydives all the time," Koreen said.
The USPA is a nonprofit that specializes in creating skydiving training programs and safety guidelines. According to Koreen, in some cases, equipment can be modified to accommodate disabled jumpers. She says it's not uncommon nowadays for disabled people — from wounded veterans to amputees — to skydive.
"Even if it's just for a couple of minutes, they feel liberated and free and can experience the same joys in life that people without disabilities can experience," Koreen said.
Officials this week announced plans for a permanent memorial in remembrance of the shootings. The memorial is expected to be located downtown at the Old Pima County Courthouse and in an adjacent park. The sites would display some of the thousands of items, including letters, candles and American flags that were placed in storage after forming makeshift memorials in the days after the shooting.
Some of the items will be on display Wednesday at libraries in Tucson.
"Like any community that experiences a tragedy, the citizens want to be connected to it in some way to show their appreciation and understanding and sympathy," said Stephen Brigham, president of the January 8 Memorial Foundation. "Everyone we talked to reinforced the importance of providing a place to go and remember that tragedy, but also a place to remember and celebrate how the community responded."
Giffords and Kelly formed their organization just weeks after the massacre in Newtown, Conn.
Since then, a divided Congress has done nothing to tighten any of the nation's gun laws. Some states, including Colorado and Delaware, pushed ahead with their own gun-control measures, while others, like Arizona, Giffords' home state, moved in the opposite direction, passing a law that requires municipalities to sell weapons surrendered at buyback programs aimed at getting more guns off the streets instead of destroying them.
Kelly said his group has signed up more than a half-million people, and between January 2013 and July 2013, they raised more than $11 million. He pointed to the successes in Colorado and Delaware in enhancing background checks.
"So we're going to have the resources to be effective in the next election cycle in 2014," he said.
Kelly is a gun owner and supporter of the Second Amendment who wishes he could work with organizations like the National Rifle Association to preserve gun rights while also keeping weapons out of the hands of dangerous criminals and the mentally unstable.
